基于微震监测的超前支承压力分布特征研究
|
摘要
为了定量研究煤矿采场超前支承压力的分布规律,采用固定工作面的方法,研究了采煤工作面前方微震事件的分布特征,在此基础上通过微震波波形分析和反演,进行了工作面前方视应力的分布特征研究.结果表明,采用固定工作面能更好的反映超前支承压力与微震监测参数的关系,同实测超前支承压力曲线一样,视应力曲线同样具有明显的单峰值结构,通过分析工作面前方视应力分布曲线可以获得描述超前支承压力分布特征的所有参数.
The distribution of micro-seismic events at the fixed work face of coal mine was studied.The distribution of the apparent stress in front of the work face was obtained by waveform analysis and inversion of the micro-seismic data.The results show that by fixing the work face the relationship between micro-seismic activity and the distribution of the lead abutment pressure can be determined.The distribution of apparent stress in front of the work face is very similar to the lead abutment pressure.The parameters of apparent stress may be used to describe the distribution of lead abutment pressure over the same region.
